What customers say
The Signature XD garners strong praise, especially for its uncompromising audio fidelity.

Know before you buy
No, you do not. These speakers feature a built-in 650-watt ICEpower amplifier, meaning they are self-powered and do not require an external power amp to reach their full potential.
The sealed enclosure design makes these speakers significantly less sensitive to room placement than ported designs. This allows for more flexibility, as they are less likely to cause boomy or muddy bass when placed closer to walls or in challenging room corners.
The Signature XD offers versatile input options, including XLR and RCA connections for preamp-level signals, as well as 5-way binding posts for high-level connections, allowing them to integrate easily into both professional and home audio setups.
This configuration allows the speaker to assign specific frequency ranges to dedicated drivers, resulting in greater clarity and a more precise soundstage. By splitting the audio spectrum into four distinct paths, the system can handle complex musical passages with significantly less distortion.
Yes, their reference-grade performance and 650-watt internal power make them an excellent choice for premium home theaters. They are capable of delivering the dynamic range and detail required for immersive cinematic experiences.
Each speaker stands 48 inches tall and weighs 110 pounds, so you will need a sturdy floor surface and enough clearance to accommodate their 12-inch width and 13.75-inch depth. Given their weight, it is recommended to have two people available for positioning.
